Aaron:

I made up what the correct way to implement a subclass of DataContainer was at 
http://api.kde.org/4.x-api/kdebase-workspace-
apidocs/libs/plasma/html/classPlasma_1_1DataContainer.html, based on reading 
through what the code is, and I said that checkForUpdate() should be called, 
rather than emitting dataUpdated directly.

Can you check that page and see what's incorrect, please?

Alex
